Providers are graded on the List only after a member submits feedback. The rating system we use is similar to a report card (with an "A" through "F" scale) and is used to grade the quality of the member's experience with a provider.
To provide members with the most relevant information, our rating system weighs feedback concerning completed work more heavily than experiences that are limited to estimates or telephone interactions. When work has been performed by a company, the rating impacts the provider's overall grade more.
Providers can't change their rating on the List and they aren't allowed to grade themselves. Only Angie's List members, through their reviews, have the power to change a company's overall grade.
